After Everything,Onto Anything

The first fully closed shoe to feature OOfoam technology! We combined the OOFOS patented footbed design you know and love with a 4-way stretch mesh upper to create an unbelievably comfortable shoe that enhances the recovery process. Take the stress off your tired soles, joints and give your feet the freedom of natural movement in a shoe you can wear all day, every day.

Revolutionary OOfoam technology absorbs 37% more impact than traditional footwear foam materials to reduce the stress on your feet and joints. The OOmg features a breakthrough in shoe construction that eliminates unnecessary layers and leaves only OOfoam between your foot and the ground. New OOtex 4-way stretch mesh upper conforms to your feet and the stretchable strap adds support over the arch without binding. These technologies combine to aid in the recovery process and create an incredibly comfortable shoe you can wear anywhere.
